If you made all the changes and it does not work I would try the brown paper trick.
Of course it really depends how the animal looks like at this point, assisting is really a call I make based on the animal's look.
Was the person you got this BP from reputable? Was the animal well started? (3 to 5 meals), has the breeder offer any help in troubleshooting the animal? Do you know how he keeps his hatchlings?
